BACKGROUND OF THE INVENTION

Various human cancer tissues have been found to correlate with the appearance of mutated KRAS gene. In some cases, the tissues also present an elevated level of Glutathione S-Tranferase Pi (GST-π) expression. (Miyanishi et al., Gastroenterology, 2001, Vol. 121:865-874, Abstract) For example, elevated serum GST-π levels were observed in patients with various gastrointestinal malignancies. (Niitsu et al., Cancer, 1989, Vol. 63, No. 2, pp. 317-323, Abstract)

GST-π is a member of a GST family of enzymes that play a role in detoxification by catalyzing the conjugation of hydrophobic and electrophilic compounds with reduced glutathione. GST-π expression can be reduced in vitro with a siRNA. (Niitsu et al., US 2014/0315975 A1)

Therapeutics for inhibition of GST-π expression will require highly potent siRNA sequences and structures.

What is needed are siRNA sequences, compounds and structures for inhibition of GST-π expression.

GST-π and RNAi Molecules

FIG. 1 shows the nucleic acid sequence of an example target human glutathione S-transferase pi (human GST-π) mRNA, which is disclosed in GenBank accession number NM_000852.3 (hGSTP1), and is 986 nucleotides in length (SEQ ID NO: 1).

One of ordinary skill in the art would understand that a reported sequence may change over time and to incorporate any changes needed in the nucleic acid molecules herein accordingly.

Embodiments of this invention can provide compositions and methods for gene silencing of GST-π expression using small nucleic acid molecules. Examples of nucleic acid molecules include molecules active in RNA interference (RNAi molecules), short interfering RNA (siRNA), double-stranded RNA (dsRNA), micro-RNA (miRNA), and short hairpin RNA (shRNA) molecules, as well as DNA-directed RNAs (ddRNA), Piwi-interacting RNAs (piRNA), and repeat associated siRNAs (rasiRNA). Such molecules are capable of mediating RNA interference against GST-π gene expression.

The composition and methods disclosed herein can also be used in treating various kinds of malignant tumors in a subject.

The nucleic acid molecules and methods of this invention may be used to down regulate the expression of genes that encode GST-π.

The compositions and methods of this invention can include one or more nucleic acid molecules, which, independently or in combination, can modulate or regulate the expression of GST-π protein and/or genes encoding GST-π proteins, proteins and/or genes encoding GST-π associated with the maintenance and/or development of diseases, conditions or disorders associated with GST-π, such as malignant tumor.

The compositions and methods of this invention are described with reference to exemplary sequences of GST-π. A person of ordinary skill in the art would understand that various aspects and embodiments of the invention are directed to any related GST-π genes, sequences, or variants, such as homolog genes and transcript variants, and polymorphisms, including single nucleotide polymorphism (SNP) associated with any GST-π genes.

In some embodiments, the compositions and methods of this invention can provide a double-stranded short interfering nucleic acid (siRNA) molecule that downregulates the expression of a GST-π gene, for example human GST-π.

A RNAi molecule of this invention can be targeted to GST-π and any homologous sequences, for example, using complementary sequences or by incorporating non-canonical base pairs, for example, mismatches and/or wobble base pairs, that can provide additional target sequences.

In instances where mismatches are identified, non-canonical base pairs, for example, mismatches and/or wobble bases can be used to generate nucleic acid molecules that target more than one gene sequence.

For example, non-canonical base pairs such as UU and CC base pairs can be used to generate nucleic acid molecules that are capable of targeting sequences for differing GST-π targets that share sequence homology. Thus, a RNAi molecule can be targeted to a nucleotide sequence that is conserved between homologous genes, and a single RNAi molecule can be used to inhibit expression of more than one gene.

In some aspects, the compositions and methods of this invention include RNAi molecules that are active against GST-π mRNA, where the RNAi molecule includes a sequence complementary to any mRNA encoding a GST-π sequence.

In some embodiments, a RNAi molecule of this disclosure can have activity against GST-π RNA, where the RNAi molecule includes a sequence complementary to an RNA having a variant GST-π encoding sequence, for example, a mutant GST-π gene known in the art to be associated with malignant tumor.

In further embodiments, a RNAi molecule of this invention can include a nucleotide sequence that can interact with a nucleotide sequence of a GST-π gene and mediate silencing of GST-π gene expression.

Examples of RNAi molecules of this invention targeted to GST-π mRNA are shown in Tables 1 and 2.

RNA Interference

RNA interference (RNAi) refers to sequence-specific post-transcriptional gene silencing in animals mediated by short interfering RNAs (siRNAs). See, e.g., Zamore et al., Cell, 2000, Vol. 101, pp. 25-33; Fire et al., Nature, 1998, Vol. 391, pp. 806811; Sharp, Genes & Development, 1999, Vol. 13, pp. 139-141.

An RNAi response in cells can be triggered by a double stranded RNA (dsRNA), although the mechanism is not yet fully understood. Certain dsRNAs in cells can undergo the action of Dicer enzyme, a ribonuclease III enzyme. See, e.g., Zamore et al., Cell, 2000, Vol. 101, pp. 25-33; Hammond et al., Nature, 2000, Vol. 404, pp. 293-296. Dicer can process the dsRNA into shorter pieces of dsRNA, which are siRNAs.

In general, siRNAs can be from about 21 to about 23 nucleotides in length and include a base pair duplex region about 19 nucleotides in length.

RNAi involves an endonuclease complex known as the RNA induced silencing complex (RISC). An siRNA has an antisense or guide strand which enters the RISC complex and mediates cleavage of a single stranded RNA target having a sequence complementary to the antisense strand of the siRNA duplex. The other strand of the siRNA is the passenger strand. Cleavage of the target RNA takes place in the middle of the region complementary to the antisense strand of the siRNA duplex See, e.g., Elbashir et al., Genes & Development, 2001, Vol. 15, pp. 188-200.

As used herein, the term “sense strand” refers to a nucleotide sequence of a siRNA molecule that is partially or fully complementary to at least a portion of a corresponding antisense strand of the siRNA molecule. The sense strand of a siRNA molecule can include a nucleic acid sequence having homology with a target nucleic acid sequence.

As used herein, the term “antisense strand” refers to a nucleotide sequence of a siRNA molecule that is partially or fully complementary to at least a portion of a target nucleic acid sequence. The antisense strand of a siRNA molecule can include a nucleic acid sequence that is complementary to at least a portion of a corresponding sense strand of the siRNA molecule.

RNAi molecules can down regulate or knock down gene expression by mediating RNA interference in a sequence-specific manner. See, e.g., Zamore et al., Cell, 2000, Vol. 101, pp. 25-33; Elbashir et al., Nature, 2001, Vol. 411, pp. 494-498; Kreutzer et al., WO2000/044895; Zernicka-Goetz et al., WO2001/36646; Fire et al., WO1999/032619; Plaetinck et al., WO2000/01846; Mello et al., WO2001/029058.

As used herein, the terms “inhibit,” “down-regulate,” or “reduce” with respect to gene expression means that the expression of the gene, or the level of mRNA molecules encoding one or more proteins, or the activity of one or more of the encoded proteins is reduced below that observed in the absence of a RNAi molecule or siRNA of this invention. For example, the level of expression, level of mRNA, or level of encoded protein activity may be reduced by at least 1%, or at least 10%, or at least 20%, or at least 50%, or at least 90%, or more from that observed in the absence of a RNAi molecule or siRNA of this invention.

RNAi molecules can also be used to knock down viral gene expression, and therefore affect viral replication.

RNAi molecules can be made from separate polynucleotide strands: a sense strand or passenger strand, and an antisense strand or guide strand. The guide and passenger strands are at least partially complementary. The guide strand and passenger strand can form a duplex region having from about 15 to about 49 base pairs.

In some embodiments, the duplex region of a siRNA can have 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, or 49 base pairs.

In certain embodiments, a RNAi molecule can be active in a RISC complex, with a length of duplex region active for RISC.

In additional embodiments, a RNAi molecule can be active as a Dicer substrate, to be converted to a RNAi molecule that can be active in a RISC complex.

In some aspects, a RNAi molecule can have complementary guide and passenger sequence portions at opposing ends of a long molecule, so that the molecule can form a duplex region with the complementary sequence portions, and the strands are linked at one end of the duplex region by either nucleotide or non-nucleotide linkers. For example, a hairpin arrangement, or a stem and loop arrangement. The linker interactions with the strands can be covalent bonds or non-covalent interactions.

A RNAi molecule of this disclosure may include a nucleotide, non-nucleotide, or mixed nucleotide/non-nucleotide linker that joins the sense region of the nucleic acid to the antisense region of the nucleic acid. A nucleotide linker can be a linker of ≧2 nucleotides in length, for example about 3, 4, 5, 6, 7, 8, 9, or 10 nucleotides in length. The nucleotide linker can be a nucleic acid aptamer. By “aptamer” or “nucleic acid aptamer” as used herein refers to a nucleic acid molecule that binds specifically to a target molecule wherein the nucleic acid molecule has sequence that includes a sequence recognized by the target molecule in its natural setting. Alternately, an aptamer can be a nucleic acid molecule that binds to a target molecule, where the target molecule does not naturally bind to a nucleic acid. For example, the aptamer can be used to bind to a ligand-binding domain of a protein, thereby preventing interaction of the naturally occurring ligand with the protein. See, e.g., Gold et al., Annu Rev Biochem, 1995, Vol. 64, pp. 763-797; Brody et al., J. Biotechnol., 2000, Vol. 74, pp. 5-13; Hermann et al., Science, 2000, Vol. 287, pp. 820-825.

Examples of a non-nucleotide linker include an abasic nucleotide, polyether, polyamine, polyamide, peptide, carbohydrate, lipid, polyhydrocarbon, or other polymeric compounds, for example polyethylene glycols such as those having from 2 to 100 ethylene glycol units. Some examples are described in Seela et al., Nucleic Acids Research, 1987, Vol. 15, pp. 3113-3129; Cload et al., J. Am. Chem. Soc., 1991, Vol. 113, pp. 6324-6326; Jaeschke et al., Tetrahedron Lett., 1993, Vol. 34, pp. 301; Arnold et al., WO1989/002439; Usman et al., WO1995/006731; Dudycz et al., WO1995/011910, and Ferentz et al., J. Am. Chem. Soc., 1991, Vol. 113, pp. 4000-4002.

A RNAi molecule can have one or more overhangs from the duplex region. The overhangs, which are non-base-paired, single strand regions, can be from one to eight nucleotides in length, or longer. An overhang can be a 3′-end overhang, wherein the 3′-end of a strand has a single strand region of from one to eight nucleotides. An overhang can be a 5′-end overhang, wherein the 5′-end of a strand has a single strand region of from one to eight nucleotides.

The overhangs of a RNAi molecule can have the same length, or can be different lengths.

A RNAi molecule can have one or more blunt ends, in which the duplex region ends with no overhang, and the strands are base paired to the end of the duplex region.

A RNAi molecule of this disclosure can have one or more blunt ends, or can have one or more overhangs, or can have a combination of a blunt end and an overhang end.

A 5′-end of a strand of a RNAi molecule may be in a blunt end, or can be in an overhang. A 3′-end of a strand of a RNAi molecule may be in a blunt end, or can be in an overhang.

A 5′-end of a strand of a RNAi molecule may be in a blunt end, while the 3′-end is in an overhang. A 3′-end of a strand of a RNAi molecule may be in a blunt end, while the 5′-end is in an overhang.

In some embodiments, both ends of a RNAi molecule are blunt ends.

In additional embodiments, both ends of a RNAi molecule have an overhang.

The overhangs at the 5′- and 3′-ends may be of different lengths.

In certain embodiments, a RNAi molecule may have a blunt end where the 5′-end of the antisense strand and the 3′-end of the sense strand do not have any overhanging nucleotides.

In further embodiments, a RNAi molecule may have a blunt end where the 3′-end of the antisense strand and the 5′-end of the sense strand do not have any overhanging nucleotides.

A RNAi molecule may have mismatches in base pairing in the duplex region.

Any nucleotide in an overhang of a RNAi molecule can be a deoxyribonucleotide, or a ribonucleotide.

One or more deoxyribonucleotides may be at the 5′-end, where the 3′-end of the other strand of the RNAi molecule may not have an overhang, or may not have a deoxyribonucleotide overhang.

One or more deoxyribonucleotides may be at the 3′-end, where the 5′-end of the other strand of the RNAi molecule may not have an overhang, or may not have a deoxyribonucleotide overhang.

In some embodiments, one or more, or all of the overhang nucleotides of a RNAi molecule may be 2′-deoxyribonucleotides.

Dicer Substrate RNAi Molecules

In some aspects, a RNAi molecule can be of a length suitable as a Dicer substrate, which can be processed to produce a RISC active RNAi molecule. See, e.g., Rossi et al., US2005/0244858.

A double stranded RNA (dsRNA) that is a Dicer substrate can be of a length sufficient such that it is processed by Dicer to produce an active RNAi molecule, and may further include one or more of the following properties: (i) the Dicer substrate dsRNA can be asymmetric, for example, having a 3′ overhang on the antisense strand, and (ii) the Dicer substrate dsRNA can have a modified 3′ end on the sense strand to direct orientation of Dicer binding and processing of the dsRNA to an active RNAi molecule.

In certain embodiments, the longest strand in a Dicer substrate dsRNA may be 24-30 nucleotides in length.

A Dicer substrate dsRNA can be symmetric or asymmetric.

In some embodiments, a Dicer substrate dsRNA can have a sense strand of 22-28 nucleotides and an antisense strand of 24-30 nucleotides.

In certain embodiments, a Dicer substrate dsRNA may have an overhang on the 3′ end of the antisense strand.

In further embodiments, a Dicer substrate dsRNA may have a sense strand 25 nucleotides in length, and an antisense strand 27 nucleotides in length, with a 2 base 3′-overhang. The overhang may be 1, 2 or 3 nucleotides in length. The sense strand may also have a 5′ phosphate.

An asymmetric Dicer substrate dsRNA may have two deoxyribonucleotides at the 3′-end of the sense strand in place of two of the ribonucleotides.

The sense strand of a Dicer substrate dsRNA may be from about 22 to about 30, or from about 22 to about 28; or from about 24 to about 30; or from about 25 to about 30; or from about 26 to about 30; or from about 26 and 29; or from about 27 to about 28 nucleotides in length.

The sense strand of a Dicer substrate dsRNA may be 22, 23, 24, 25, 26, 27, 28, 29 or 30 nucleotides in length.

In certain embodiments, a Dicer substrate dsRNA may have sense and antisense strands that are 26 to 29 nucleotides in length.

In certain embodiments, a Dicer substrate dsRNA may have sense and antisense strands that are 27 nucleotides in length.

The sense and antisense strands of a Dicer substrate dsRNA may be the same length as in being blunt ended, or different lengths as in having overhangs, or may have a blunt end and an overhang.

A Dicer substrate dsRNA may have a duplex region of 19, 20, 21, 22, 23, 24, 25, 26 or 27 nucleotides in length.

The antisense strand of a Dicer substrate dsRNA may have any sequence that anneals to at least a portion of the sequence of the sense strand under biological conditions, such as within the cytoplasm of a eukaryotic cell.

A Dicer substrate with a sense and an antisense strand can be linked by a third structure, such as a linker group or a linker oligonucleotide. The linker connects the two strands of the dsRNA, for example, so that a hairpin is formed upon annealing.

The sense and antisense strands of a Dicer substrate are in general complementary, but may have mismatches in base pairing.

In some embodiments, a Dicer substrate dsRNA can be asymmetric such that the sense strand has 22-28 nucleotides and the antisense strand has 24-30 nucleotides.

A region of one of the strands, particularly the antisense strand, of the Dicer substrate dsRNA may have a sequence length of at least 19 nucleotides, wherein these nucleotides are in the 21-nucleotide region adjacent to the 3′ end of the antisense strand and are sufficiently complementary to a nucleotide sequence of the RNA produced from the target gene.

An antisense strand of a Dicer substrate dsRNA can have from 1 to 9 ribonucleotides on the 5′-end, to give a length of 22-28 nucleotides. When the antisense strand has a length of 21 nucleotides, then 1-7 ribonucleotides, or 2-5 ribonucleotides, or 4 ribonucleotides may be added on the 3′-end. The added ribonucleotides may have any sequence.

A sense strand of a Dicer substrate dsRNA may have 24-30 nucleotides. The sense strand may be substantially complementary with the antisense strand to anneal to the antisense strand under biological conditions.

Example 5

FIG. 4 shows tumor inhibition efficacy for GST-π siRNA (BU02). A pancreatic cancer xenograft model was utilized with a relatively low dose at 0.75 mg/kg of siRNA targeted to GST-π. The GST-π siRNA demonstrated significant and unexpectedly advantageous tumor inhibition efficacy at day 28.

In this experiment, A549 and PANC-1 cell lines were obtained from ATCC. The cell suspension was mixed well with ice thawed BD matrigel at 1:1 ratio for injection. Each mouse, athymic nude female mice, 6 to 8 weeks, Charles River, was inoculated subcutaneously in the right flank with 0.1 ml of an inoculum of 2×10⁶ (A549) or 2.5×10⁶ (PANC-1) cells using a 25 G needle and syringe (1 inoculum per mouse). Mice were anesthetized for inoculation. On the day when the established tumors reached approximately 250-350 mm³ (A549) or 150-250 mm³ (PANC-1) animals were subjected to bolus injection through tail vein. Animals were sacrificed by overdosed CO₂ and tumors dissected at different time points following the dosing. Tumors were first wet weighted, and then separated into three parts for measurement of GST-π knockdown, biodistribution of siRNA, and biomarker analysis. The samples were snap frozen in liquid nitrogen and stored at −80° C. until ready to be processed for bioanalysis.

Example 6 Orthotopic A549 Lung Cancer Mouse Model

The GST-π siRNAs of this invention can exhibit profound reduction of orthotopic lung cancer tumors in vivo. In this example, a GST-π siRNA provided gene knockdown potency in vivo when administered in a liposomal formulation to the orthotopic lung cancer tumors in athymic nude mice.

In general, an orthotopic tumor model can exhibit direct clinical relevance for drug efficacy and potency, as well as improved predictive ability. In the orthotopic tumor model, tumor cells are implanted directly into the same kind of organ from which the cells originated.

The anti-tumor efficacy of the siRNA formulation against human lung cancer A549 was evaluated by comparing the final primary tumor weights measured at necropsy for the treatment group and the vehicle control group.

Orthotopic lung cancer tumor inhibition was observed in vivo for a GST-π siRNA based on structure BU2 (SEQ ID NOs:1276 and 1341). An orthotopic A549 lung cancer mouse model was utilized with a relatively low dose at 2 mg/kg of the siRNA targeted to GST-π.

The GST-π siRNA showed significant and unexpectedly advantageous lung tumor inhibition efficacy in this six-week study. After 43 days, the GST-π siRNA showed markedly advantageous tumor inhibition efficacy, with final tumor average weights significantly reduced by 2.8-fold as compared to control.

For this study, male NCr nu/nu mice, 5-6 weeks old, were used. The experimental animals were maintained in a HEPA filtered environment during the experimental period. The siRNA formulations were stored at 4° C. before use, and warmed to room temperature 10 minutes prior to injection in mouse.

For this A549 human lung cancer orthotopic model, on the day of surgical orthotopic implantation (SOI), the stock tumors were harvested from the subcutaneous site of animals bearing A549 tumor xenograft and placed in RPMI-1640 medium. Necrotic tissues were removed and viable tissues were cut into 1.5-2 mm³ pieces. The animals were anesthetized with isoflurane inhalation and the surgical area was sterilized with iodine and alcohol. A transverse incision approximately 1.5 cm long was made in the left chest wall of the mouse using a pair of surgical scissors. An intercostal incision was made between the third and the fourth rib and the left lung was exposed. One A549 tumor fragment was transplanted to the surface of the lung with an 8-0 surgical suture (nylon). The chest wall was closed with a 6-0 surgical suture (silk). The lung was re-inflated by intrathoracic puncture using a 3 cc syringe with a 25 G×1½ needle to draw out the remaining air in the chest cavity. The chest wall was closed with a 6-0 surgical silk suture. All procedures of the operation described above were performed with a 7× magnification microscope under HEPA filtered laminar flow hoods.

Three days after tumor implantation, the model tumor-bearing mice were randomly divided into groups of ten mice per group. For the group of interest, treatment of the ten mice was initiated three days after tumor implantation.

For the group of interest, the formulation was (Ionizable lipid:cholesterol:DOPE:DOPC:DPPE-PEG-2K:DSPE-PEG-2K), a liposomal composition. The liposomes encapsulated the GST-π siRNA.

For the study endpoint, the experimental mice were sacrificed forty-two days after treatment initiation. Primary tumors were excised and weighed on an electronic balance for subsequent analysis.

For an estimation of compound toxicity, the mean body weight of the mice in the treated and control groups was maintained within the normal range during the entire experimental period. Other symptoms of toxicity were not observed in the mice.

Example 7

Effect of small interfering RNA (siRNA) targeting GST-π on A549 cell growth in nude mice and angiogenesis on chorioallantoic membrane (CAM) assay. Three pairs of GST-π siRNA-plasmid and non-silencing-plasmid are constructed, and transfected into A549 cells through LIPOFECTAMINE 2000, respectively. The most effective pair of GST-π siRNA-plasmid is selected by ELISA and real-time RT-PCR. A549 cells are transfected with selected GST-π siRNA-plasmid, A549 cells are transfected with non-silencing-plasmid, and A549 cells without transfection are inoculated into nude mice, respectively. Chick embryos are randomly divided into four groups and CAM is treated by different solutions for 48 h: culture media DMEM as negative control group, un-transfected A549 cell culture supernatants as positive control group, GST-π siRNA A549 cell culture supernatants as GST-π siRNA group and non-silencing siRNA A549 cell culture supernatants as non-silencing siRNA group. The CAMs were harvested on day 12 for microscopic assays.

Compared with control group, GST-π siRNA-plasmid induces reduction in GST-π secretion by A549 cells accompanied by reduction in GST-π mRNA. Compared with non-silencing siRNA group, the mean tumor volume of murine xenograft is reduced in GST-π siRNA group; time for xenografts growing to 50 mm³ is delayed. GST-π contents in xenograft are reduced. In CAM assays, GST-π content is zero in negative group, and in GST-π siRNA group is reduced by 20-70% compared to non-silencing siRNA group or positive group; vessels branch points of CAM in GST-π siRNA group or non-silencing siRNA group or positive group are increased compared with negative group; total vessel length of CAM in GST-π siRNA group is increased compared with negative group, while in non-silencing siRNA group or positive group it is increased. Compared with negative control group, the proliferation of microvessels is increased when cell culture supernatant with GST-π is added in GST-π siRNA group, significant proliferated vessels are observed in non-silencing siRNA group or positive group.

Cell culture. The human non-small cell lung carcinoma cell line, A549 is cultured in F-12K medium (ATCC) supplemented with 10% FBS (FBS, Invitrogen) at 37° C. in a humidified atmosphere with 5% CO₂. The cells stably expressing control, or GSTπ siRNAs are generated by transducing A549TR cells with the respective lentiviral transduction particles as per manufacturer's instructions (Sigma-Aldrich). Resistant clones are selected in 2.5 μg/mL puromycin (Invivogen) for 12 d, isolated using cloning cylinders, and subsequently expanded and maintained in puromycin-containing medium.

Example 9

GST-π targeted siRNA results in profound regression of tumor volume in vivo.

A lipid formulation is used to encapsulate and deliver siRNA in nanoparticles to xenografts of human A549 lung cancer cells in scid mice. The xenografts are tested to identify the presence of KRAS mutations or aberrant levels of expression compared to normal cells. When tumors became established (>100 mm³), mice are treated with either GST-π targeted siRNA or Control (non-specific) siRNA every 2 days for 2 weeks. The trial is halted when the control group has to be euthanized.

Results: Treatment with GST-π targeted siRNA prevents tumor expansion and results in dramatic tumor volume reduction.

The tumors that are recovered are sectioned and visualized by TUNEL staining. GST-π targeted siRNA-treated tumors display significantly higher levels of apoptosis. RNA is extracted from the tumors, and real-time PCR is performed to examine specific knockdown of GST-π.

Results: Treatment with GST-π targeted siRNA dramatically reduces expression of GST-π in vivo.

Tumor inhibition efficacy was observed for a GST-π siRNA (SEQ ID NOs:1276 and 1341). Dose dependent knockdown of GST-π mRNA was observed in vivo with the siRNA targeted to GST-π. A cancer xenograft model was utilized with a siRNA targeted to GST-π.

The GST-π siRNA showed significant and unexpectedly advantageous tumor inhibition efficacy within a few days after administration. Treatment with a GST-π siRNA resulted in significant reduction of GST-π mRNA expression 4 days after injection in a lipid formulation. At the higher dose of 4 mg/kg, significant reduction of about 40% was detected 24 hours after injection.

The GST-π siRNA was administered in a single injection of 10 mL/kg of a liposomal formulation having the composition (Ionizable lipid:Cholesterol:DOPE:DOPC:DPPE-PEG-2K) (25:30:20:20:5).

For the cancer xenograft model, an A549 cell line was obtained from ATCC. The cells were maintained in RPMI-1640 supplemented with 10% Fetal Bovine Serum and 100 U/ml penicillin and 100 μg/ml streptomycin. Cells were split 48 hrs before inoculation so that cells were in log phase growth when harvested. Cells were lightly trypsinized with trypsin-EDTA and harvested from tissue culture. The number of viable cells was counted and determined in a hemocytometer in the presence of trypan blue (only viable cells are counted). The cells were resuspended to a concentration of 4×10⁷/ml in RPMI media without serum. Then the cell suspension was mixed well with ice thawed BD matrigel at 1:1 ratio for injection.

Mice were Charles River Laboratory Athymic Nude (nu/nu) Female Mice, immuno-compromised, 6-8 weeks old, 3 mice per group.

For tumor model preparation, each mouse was inoculated subcutaneously in the right flank with 0.1 ml an inoculum of 2×10⁶ of A549 cells using a 25 G needle and syringe, one inoculum per mouse. Mice were not anesthetized for inoculation.

For tumor volume measurements and randomization, tumor size was measured to the nearest 0.1 mm. Tumor volumes were calculated using the formula: Tumor volume=length×width²/2. Tumor volumes were monitored twice a week. Once the established tumors reached approximately 350-600 mm³, the mice were assigned into groups with varied time points. On the same day, test articles were administered according to the dosing regimen.

For dosage administration, on the day when the established tumors reached approximately 350-600 mm³, the test articles were taken out from 4° C. fridge. Before being applied to syringes, the bottle containing formulation was reverted by hand for a few times to make a homogeneous solution.

For body weight, mice were weighed to the nearest 0.1 g. Body weights were monitored and recorded twice for weeks, for the rest of weeks, including the day of study termination.

For tumors collection, animals were sacrificed by overdosed CO₂ and tumors were dissected at 0, 24, 48, 72, 96 (optional), and 168 hours following the dosing. Tumors were first wet weighted, and then separated into three parts for KD, distribution and biomarker analysis. The samples were snap frozen in liquid nitrogen and stored at −80° C. until ready to be processed.
